_unlock_file

Unlocks a file, allowing other processes to access the file.

Syntax

void _unlock_file(
   FILE* file
);

Parameters

file
File handle.

Remarks

The _unlock_file function unlocks the file specified by file. Unlocking a file allows access to the file by other processes. This function shouldn't be called unless _lock_file was previously called on the file pointer. Calling _unlock_file on a file that isn't locked may result in a deadlock. For an example, see _lock_file.

By default, this function's global state is scoped to the application. To change this behavior, see Global state in the CRT.
